“…Several questions must be considered in this step. Firstly, the presented algorithm continues the line of work developed by the authors in previous papers, see [3,4,78], solving the common bottleneck caused by the dependence of the time of computation on the complexity of the model at orders O((c + 1) 3d ) and O((c + 1) d ). Now, the dependence on the dimension has an expression of d•2 d .…”

“…However, it changes with direction for anisotropic materials, as shown for composite material layup of a 61.5 m and 100 m long blade in [24,33]. In this study, blade properties, required to achieve a desired mass, stiffness, and modal response, are optimized using a genetic algorithm [3,32], discussed later in Section 5. The blade thickness (t) and its gradient (S) from the optimized design solution (DS) are used to calculate the mechanical properties of each blade airfoil, as shown in this section.…”

“…Similarly, (q2-q3) and (q3-q2) is the shear flow acting on a length-to-thickness ratio a23 and a23 along the wall FD. Thus, solving Equation (30) to (32) for q1, q2, and q3 and Equation (29) for T, the torsional stiffness (J) for an airfoil stiffened with two webs can be obtained through Equation (22)…”

“…This study presents an FE integrated genetic algorithm (GA) based blade optimisation. GA is a problemindependent optimisation method, proven to robustly solve complex eigenvalue problems [16], optimise wind turbine tower performance [3], composite blade shapes [24,25], and wind farm layouts [26][27][28]. The objective function is defined in terms of blade mass and its location, moment of inertia, and frequencies (flapwise and edgewise).…”
